Using Remote Office 9150 stations
Online mode
When in online mode, calls initiated on the host call appearance key are directed
through the host PBX. Any long distance charges associated with calls placed
through the PBX over the PSTN are charged to the host PBX site. The display
on all digital telephones shows "Online Mode."
Offline mode
When in offline mode, you cannot place calls through the host PBX over either
the IP network or PSTN. You can only place calls through your local telephone
service provider if your station has been granted locally controlled call
capability. The display on all digital telephones show "Offline Mode."
Why offline mode is important
Your organization is concerned about telephone costs and, as such, wants to
ensure that the ISDN BRI line at your site is used for host-controlled calls during
business hours only. This is especially important when the ISDN BRI
connection between the host PBX and your site is defined as permanent (always
on) rather than on demand. A permanent ISDN BRI connection means the line
remains active all the time and incurs charges unless it is put into offline mode.
What controls the online and offline modes
The online and offline modes can be controlled by one or both of the following:
n
the online/offline schedule configured for your site on the RLC at the host
PBX
n
special prefix (SPRE) codes configured on the Remote Office 9150 unit at
your site
Online/offline schedule at host PBX
If telephone service costs are an issue, your telecom network administrator
defines an online/offline schedule on the RLC port to which your site is
assigned. The times at which your site is put into online or offline mode are
processed by the host PBX.
